GLASS BOTTLE AND GLASS STOPPER.

SPECIFICATION forming part of Letters Patent No. 225,654, dated March16, 1880.

Application filed February 6, 1880.

To all whom it may concern:

Be it known that I, ROBERT PEARSALL SMITH, a citizen of the UnitedStates, residing in Philadelphia, Pennsylvania, have invented anImprovement in Glass Bottles and Glass Covers for the same, of which thefollowing is a specification.

The objects of my invention are, first, to

make a glass bottle-cover in the peculiar manner described hereinafter,for the permanent retention therein of a cork ring or lining; and,second, to so combine the said cover and its cork ring with the neck ofa bottle, and with a shoulder thereon, that while the cover will fitsufficiently tight to the upper edge of the neck of the bottle it can bereadily detached from the same.

In the accompanying drawings, Figure 1 is a view, partly in section, ofmy improved bot- 2o tle and of the cover, wholly in section; and

Fig. 2, the same as Fig. 1, with the cover applied to the mouth of thebottle.

The bottles to which my invention is most applicable are such as areused by druggists and others for putting up pomades, cosmetics, &c., insmall quantities for purchasers.

A is the body of the bottle; a, the neck, which is so constructed as toform an external shoulder, b.

The flange c of the glass cover B is, preferably, made on aslight taper,so as to be larger in diameter below than above, and this flangeterminates at its lower edge in an internallyprojecting annular rib, f.

At the junction of the flange c with the top m of the cover there is aninternal recess, a, bounded laterally in one direction by the flange e,and in the other by an annular rib, p, projecting downward from the topm of the cover.

Within the cover, and bearing against the interior of the flange c, is aring, D, of cork, or a-strip of cork bent to the form of a ring, thelower edge of which bears on the internal 5 rib, f, the upper edgefitting into the annular recess it. After this cork ring has been forcedtight into its place it cannot be easily removed, as it is confinedvertically by the rib f, and laterally in the annular recess n.

It should be understood that the cover, while intended to fit tightenough, through the medium of the cork ring, to exclude air from theinterior of the bottle, should admit of being detached with a veryslight effort, the cork fitting tight enough to the neck to permit thecover to have a slight frictional hold of the same, so that it cannot beshaken loose; but the cork should not prevent the ready application ofthe cover to the neck of the bottle.

In order to meet these requirements, the cork ring D is taperingthat is,the ring is larger in internal diameter below than abovewhile the neckof the bottle may be cylindrical, or nearly so; hence in applying thecover it will fit freely over the neck in the first instance; but ondepressing the cover the cork will embrace the upper edge of the neck.To permit the cover to be depressed to an unlimited extent, however,would result, in many cases, in too tight a fit; hence the externalshoulder, b, on the bottle, on which the lower edge of the glass coverbears when properly fitted to the neck, and which limits the penetrationof the neck into the cover. 7 5

The upper edge of the neck, when the cover is depressed to its place,will indent the interior of the cork at m, where a permanent hearing forthe edge of the neck is made, and this bearing insures a proper tightjoint and a sufficient frictional hold of the cover on the neck withoutpreventing the ready removal of the cover with a very slight efiort.

I am aware that covers have been made with elastic linings to fit to theexterior of the necks of vessels. This, therefore, I do not claim,broadly; but

I claim as my invention 1. The glass cover B, having an internal annularrecess, n, at the junction of the flange 0 c with the top m, and aninternal rib, f, projecting from the lower edge of the said flange,
